Our Family

Ellipse Theory. was created by our founder, Carsten Hallas, together with co-founder Lucas Clausen. Carsten has worked in luxury interiors for over 50 years, designing spaces and products for high-end projects around the world. In 2025, we started Ellipse Theory to bring that same level of design and attention to detail to cordless lighting,made to feel beautiful in the home, and built to work in real life.
